What defines an embedded system?

An embedded system is defined as a computing system designed to perform a specific dedicated function or set of functions within a larger system. This distinct characteristic sets embedded systems apart from general-purpose computers, which are designed to handle a wide range of tasks. Embedded systems are typically found within devices such as appliances, automobiles, medical equipment, and industrial machines, where they manage or control specific operations.

The primary focus of an embedded system is efficiency and reliability in executing its dedicated tasks, often with constraints such as size, power consumption, and cost. This dedication to a specific function allows for optimization of the system's performance, ensuring that it meets the requirements of the application it supports.
